What is the cause of tsunami?
A tsunami is a series of extremely long waves caused by a large and sudden displacement of the ocean, usually the result of an earthquake below or near the ocean floor. This force creates waves that radiate outward in all directions away from their source, sometimes crossing entire ocean basins.
What is tsunami its causes and effects?
Tsunami is waves caused by a sudden movement of the ocean surface due to earthquakes, landslides on the sea floor, land slumping into the ocean, large volcanic eruptions or meteorite impact in the ocean. It destroys human life and livelihood and also causes the loss of natural resources.
How is tsunami caused Class 7?
During a storm the winds blowing at a very high speed and form huge waves. These waves may cause tremendous destruction. An earthquake, a volcanic eruption or underwater landslides can shift large amount of ocean water. As a result a huge tidal wave called tsunami, that may be as high as, 15 m., is formed.

Similarly, the greatest tsunami in Washington, Oregon, and California written history originated off Alaska with tectonic displacement during the 1964 earthquake. Judging from geologic records of predecessors to the 1964 earthquake during the last 6,000 years (Fig. 3-3c), 4 ocean-wide tsunamis from the 1964 source recur at irregular intervals averaging close to
